nism, and more particularly it relates to' mechanism adapted to collectand deliver sheets which have been cut from traveling webs upon whichprinting has been effected.

One of the important objects of the invention is to provide mechanism ofthe above character which will be simple in construction and entirelyreliable in operation.

A further object of my invention is to provide means whereby sheets mayhe cut from traveling webs and superimposed one upon another, such thatwhen a predetermined number thereof have been placed in superimposedrelation they may be carried collectively along the accumulating tablein a manner that will in nowise interfere with the delivery of freshsheets upon said table.

Other objects will be in part obvious and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings, wherein are illustrated two of the variouspossible embodiments of this invention,-Figure -1 is a view in sideelevation of a portion of one of the embodiments thereof. Fig. 2 is aview in perspective showing the means employed for carrying the cutsheets along the accumulating table.

Fig. 10 is a view in perspective of the means employedfor registering the sheets one upon another. Fig. 11 is a top plan viewof the accumulating table and the mechanism associated therewith.

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

Referring now to the drawings, wherein I have shown two embodiments ofmy invention arranged for use with printing presses adapted to printupon traveling webs, from which slips or sheets for sales books are tobe cut, 1 indicates a base from which rises a standard or upright 2,which forms a support for the delivery mechanism, a portion of thesupporting frame work of which is shown at 3. Extending forwardly fromthe frame work and supported thereby is a table -l upon which the cutsheets are delivered from the printing mechanism. This table, as shown,has extending through the rear portion thereof a plurality oflongitudinal slots 5, and at its forward portion is' provided with aplurality of lateral or transversely extending slots (3. Feed rollersfor delivering the printed webs are shown at 7 and'b respectively, andco-acting with these feed rollers are spring-pressed auxiliary feedrollers 9 and 10 respectively, which serve to hold the traveling webs incontact with the positively driven feed rollers.

Journaled in an upward extension of the frame work is a cylinder 11provided with a knife 12, which co-acts with a knife 13 fixed in theframe and at each. rotation severs sheets from the webs which are beingdelivered by the feed rollers. The shaft 1 of cylinder 11 has a bevelgear 15 fixed thereon. This gear meshes with a bevel gear 16 fixed uponmain driving shaft 17. It will be understood that upon each rotation ofcylinder 11 knife 12 is brought into contact with the webs, which arepassing over knife 13, and effects the cutting of the webs into sheets.The cut sheets, which then tend to fall by gravity upon table 4, areengaged and depressed by a finger or whipper 18 clamped upon a shaft 19supported in forward. extensions 20 of the frame work. Extensions 20 aresupported intermediate their ends'by means of uprights 21 rising fromthe table. Finger 18, which is spring-pressed in an upward direction, isoscillated by means ofv a crank arm 22. Crank arm 22 is actuated bymeans of .a link 23 which co-acts with an eccentric 24 upon shaft 14 ofcylinder 11. The cut sheets fall upon the table between a fixed gage orabutment 25 adjustably supported thereon and a reciprocating jogger 26.This jogger, which is adapted to be adjusted toward gage or abutment 25by means of adjusting screw 27, has attached thereto as at 28 and 29 theinner legs of a pair of bell crank levers 30 and 31 respectively. Theouter legs of these bell crank levers are provided with pins whichextend through a reciprocating rod 32, as clearly shown in Fig. 10 ofthedrawings. Rod 32 passes through a lug 33 and is held in the positionshown by means of an extensile spring 34 coiled thereabout, whichengages a collar 35 fixed upon said rod. The outer end of the rod whichis enlarged as shown, is adapted to be engaged by the free end of alever 36 pivotally mounted at 37 in the frame work of the machine.

The opposite end of lever 36 is engaged by a cam 38 upon feed roll 8,said cam during the rotation of said feed roll operating to vibrate saidlever, which in turn vibrates rod 32. As will be understood, thevibrating of rod 32 causes jogger 26 to move toward and from the sheets,which, falling from the knives, are being deposited upon the table, andby its engagement with the edges thereof jogs them into registry oneupon another. A jogger simi-' lar to that shown in Fig. 10 is providedat the rear portion of the table, and is operated by means of a rod 39also engaged by lever 36 and vibrated thereby in a. similar manner.

Depending from extension 20 is a pivotally mounted plate 40 which hangsin proximity to the forward end of the sheets upon the table and servesto limit their forward movement as they drop thereon. This plate, aswill be apparent, swings freely upon its pivot and permits the sheets tobe delivered thereunder by the ejecting mechanism presently to bedescribed.

Sliding in ways provided beneath table 4 is a reciprocating carriage 41,and fixed upon a shaft 42 extending transversely of this carriage are apair of ejector fingers 43. One of these ejector fingers is arrangedbeneath each of the longitudinally extending slots 5 of the table, andsaid fingers when shaft42 is rotated are adapted to be projected throughsaid slots into position to engage With the sheets supported upon thetable. Ejector fingers 43 are constantly urged to a reclining positionagainst pads 44 by means of a spring 45 coiled about shaft 42,, oneoendof which is attached to the carriage and the other is attached to atension-adjusting device 46 mounted upon the shaft. Shaft 42 has alsomounted there-- on a catch 47 which when engaged by a trigger 48pivotally mounted at 49 upon ward, to engage one of the ejector fingersand force them to an upright position to permit trigger 48 to takebehind catch 47. Table 4 is also provided at its intermediate portionwith another cam 52 which extends laterally therefrom. This cam, whenthe carriage moves to its forward position, as when a pile of sheets isbeing carried along the table, engages under the forward end 53 oftrigger 48 and raises the same, whereupon spring 45, acting throughshaft 42, will force the ejector fingers to a reclining position beneaththe table.

The means employed in the embodiment shown in Fig. '1 for reciprocatingthe carriage backward and forward beneath table 4 comprises a lever 54pivotally supported in upright bracket 55 erectedupon the base of themachine, said lever at its upper portion being connected to the carriageby means of a pivotally mounted link 56. Lever 54 is urged to projectthe carriage in a forward direction by means of spring 57 one end ofwhich is secured thereto at its lower portion, the opposite end of saidspring being fixed in. one of brackets 55. Carriage 41 is forced in arearward direction against the influence of spring 57 by means of aperipheral cam 58 fast upon a shaft 59 which is journaled in an upright(30 erected upon the base, said cam acting upon an adjustable block 61secured by means of a bolt 62 in a link (33 which has a pivotalconnection at 64 with lever Cam 58 is abruptly stepped as at 65, and atthe end of each complete rotation of said cam, block ()1 rides off theperiphery of the cam. which permits spring 57 to swing lever 54 upon itspivotal support and move the car riage in a forward direction. Shaft .59of cam 58 is provided with a bevel gear ()6 which meshes with a bevelgear 6.7 upon an upright shaft 68 journaled at its lower end in upright60 and at its upper end in a suitable journal provided in table 4. Thisshaft at its upper end is provided with a worm wheel 69"which mesheswith a worm wheel 70 upon a shaft 71, which is driven by means of a carwheel 72 meshing with a gear wheel 3 fixed upon the shaft of cylinder11. By means of this construction it will be seen that carriage 41 willbe projected quickly in a forward direction to carry the superimposedsheets along the table by means of ejector fingers 43, and will then begiven a slow recovery movement while fresh sheets are being depositedthereon.

In Figs. 7, 8 and 9 I have shown a slightly different embodiment of thecarriage reciprocating means, in that the spring-pressed lever ishorizontally disposed instead of being vertically disposed, as shown inFig. 1. In this embodiment a lever 73 is pivoted at 7 1 beneath thetable, and is urged to ove the carriage in a forward direction by meansof an extensile spring 75 which encircles the stem of a rod 76 slidablymounted in a lug 77 fastened to the edge of the table and is pivotallyconnected at its opposite end in said lever. The outer end of lever 73is pivotally connected with the link 78, the intermediate portion ofwhich carries an antifriction roll 7 9 which rides upon the periphery ofa stepped cam 80 similar to that represented by 58 in Fig. 1. This camis driven by means of a gear wheel 81 which is driven by means of a worm82 fixed upon shaft 14. This mechanism, as that shown in Fig. 1,operates to reciprocate the carriage backward and forward to carry thebook of loose sheets along the table to such position as will permit itto be conveyed therefrom and finally discharged from the table bymechanism which I shall now proceed to describe.

The book of loose sheets, when carried along table -l in a forwarddirection, is deposited over the transversely extending slots 6 inposition to be engaged and lifted by a plurality of rails 83, one ofwhich is provided under each of said slots. Rails 83 are spaced apartand connected together by members 81 extending transversely thereof andsecured to the outside rails by means of screws 85. Journaled inbrackets 86 depending from the forward portion of the table is a rockershaft 87. This rocker shaft is provided with a plurality of laterallyextending spindles upon which are mounted wheels 88. said wheels formingsupports for the middle one of rails 83. Shaft 87 has also a spindleextending in a direction opposite to those which support wheels 88, saidspindle carrying an anti-friction roller 89. Coopcrating withanti-friction roller 89 is a cam wheel 90 fixed upon a shaft 91 suitablyjournaled beneath the carriage, said shaft'having also fixed thereon agear wheel 92 which meshes with a pinion 93 of a countershaft 94. Thiscountershaft is provided with a gear Wheel 95 which meshes with and isdriven by a gear wheel fixed upon main driving shaft 17. The rotation ofcam 90 causes the raised portion thereof to swing rocker shaft 87, whichlifts wheels 88 and causes rails 83 to be projected upward through theslots, whereupon they in turn lift the sheets which have been deliveredthereover by the reciprocating carriage. Rails 83 when projected upwardthrough the slots of the table, are caused to move longitudinally tocarry the sheets from the table by means of a crank arm 96 fixed uponshaft 91, which carries cam 90, said crank being connected with therails by means of a link 97 pivotally mounted to the end of the crank at98 and to the middle of the rails at 99. This cam and crank mechanismcauses an oscillatory movement of said rails, and effects the carryingof the sheets laterally along the table, clearing the way for a freshbook of sheets to be delivered over slots 5 by the reciprocatingcarriage.

Having thus described my invention, the operation thereof may now beunderstood. Cylinder 11, carrying knife 12 being con-- stantly rotated,co-acts with knife 13 to cut sheets of predetermined length from thewebs, which are delivered thereto by means of feed rollers. These sheetsthen pass beneath cylinder 11 and are struck and depressed by means offinger or whipper 18, whereupon they fall upon table 4 in superimposedrelation, the forward movement of the sheets being arrested by plate 40and the edges of the sheet being jogged into registry by the joggers,one of which is shown at '26. The mechanism is so adjusted that whensheets suflicient in number to form a book of a given number of sheetshave been deposited upon the table, carriage 9 will be at its rearwardposition, and the ejector fingers, which have been held in a depressedposition by means of spring 45, are engaged by cam 51 and forced to anupright position, where they are held by the engagement of trigger 48with catch 17. At this point block 61 in the embodiment shown in Fig. l,or anti-friction roller 8 in the embodiment shown in Fig. 9, ride offthe stepped portions of their respective cams, whereupon thespring-actuated levers carry the carriage quickly in a forward directionand move the book of loose sheets along the table, the pivotally mountedplate swinging upon its pivot to allow said sheets to pass thereunder.The engagement of trigger 48 with cam 52 when the carriage reaches theend of its forward movement releases the trigger 48 and causes spring 45to force the ejector fingers to an inclined position beneath the table,said ejector fingers remaining in such position until again forced to anupright position, as when another book of sheets is ready to be carriedalong the table. As each book of loose sheets is delivered over slots 6the oscillating rails lift the same, and while lifting said book carrythe same in a lateral direction from the table, where it may be graspedby the hand of theoperator.

It will therefore be seen that I have provided mechanism adapted toattain the objects sought in an exceedingly simple and effective manner.The cut sheets being accurately registered one upon another, aredelivered in the same condition from the table, and in such form as willpermit them to be bound or fastened together in book form withoutfurther manipulation.

While I have shown my invention as applied to a press of the above type,it will be understood that it may be adapted to other forms of presses,although the same is of peculiar value in the relation shown.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative and not in a limiting sense.
